Application filed July 31, 1920. Serial No. 400,426.

1/ 0 all to 7mm it may concern Be it known that I, FRED M. Swnnrz, acitizen or the United States, residing at Providence, in the county ofProvidence and State of Rhode island, have invented certain new anduseful Improvements in Clasps, of which the following is aspeciiication. v

My invention relates to that class of lingerie and hair clasps and thelike that comprise relatively movable jaws carrying an intermediatespring bearing member.

The principal objects of the present invention are simplicity, strengthand inexpensiveness of construction; the avoidance of the use of solderin attaching the bearing member; the complete housing of the pintle; andthe disposition of the inner end of the bearing member in such a manneras not to catch in the material clasped.

My invention consists in the means and mechanism for producing theresults above specified substantially as hereinafter described andclaimed and as shown in the accompanying drawings which form a part ofthis specification, and in which Figure 1 is a plan view of the blankfrom which the base and bearing member and their bearing is formed,

Fig. 2, a side elevation of the same after bending,

Fig. 3, a bottom plan view of the tongue,

Fig. at, a side elevation of the complete clasp closed, I

ll 5, a plan view of the same open, showing a portion of the tonguebroken away, and

Fig. 6, an enlarged section on line 6--6 of Fig. 5.

Similar reference characters indicate similar parts throughout theviews.

in the construction illustrated a blank, suchas shown in l, is out fromthin res silicnt metal comprising an oblongportion or strip 9 providedat one end with a longitudinally disposed notch or slot 10. Extendingcentrally of the other end of the portion 9 is narrow portion or neck 12extending to a somewhat broader oblong portion. 13 having on its outerend a linger F 14;. line blank is bent with the portion 9 forming thebase or lower jaw oi the clasp; the portion 13 forming; the arched bowor resilient bearing member; the portion 12. a circular loop; and thefree end of the p01" tion 9 curled to form a tubular eye 15 Whose slot10 loosely receives therethrough the tinge 14.

The loop 12 embraces a pivot member, which is also embraced by spacedinturned sleeves 18 which are integral with and project from one end ofan arched resilient tongue or jaw 20 whose opposite end is inwardlycurved to "form a hoolr 21 adapted to snap over the tube 15.

The material to be clasped is embraced between the tongue 20 and themember 13, the hook 21. serving as the catch for fastening the tongueafter insertion of the mater. The clamping material is protected fromcontact at every point from the pivot 16 by virtue of the sleeves l8 andthe loop 12, and there are no projecting parts at or adjacent the hingeto catch in the clasped material. The integral character of the loop12and its relation to the members 9 and 13 impart great strength to theentire structure, and the use of solder is avoided.

it claim In a clasp, stationary aw comprising a base, on archedresilient bearing arm, and a circular loop uniting one end of the basewith the liiearing arm. a loop integral with the othe end of the baseprovided with a slotarlaptcd to loosely receive the free end oi the arm,pivot member embraced by the loop, a movablej aw, sleeves on the movablejaw embracing; the pivot member, and a hook on the mo *able jaw engagingthe second loop.

In testimony whereof I signature.

have atiixed my FRED M. S /VARTZ.
